Randy,

10.238 MHz was very likely used for GPS applications. With GPS, it is
more important to keep LO harmonics away from the L1 input frequency
than to use any particular round frequency. The IF can be anything
suitable, as the baseband data is recovered using an NCO which corrects
for LO offset and drift, as well as satellite Doppler.

Other common GPS frequencies are 10.949297 MHz, 16.368 MHz and so on.
